Procedure

To a solution of N1-benzyl-4-methyl-benzene-1,2-diamine (1.24 mmol) and triethylamine (0.26 mL, 1.86 mmol) in dry DMF (5 mL), was added boc-D-valine (296 mg, 1.36 mmol) followed by TBTU (400 mg, 1.24 mmol). The reaction mixture was stirred at room temperature overnight. Ethyl acetate was added. The organic layer was washed with saturated NaHCO3, dried over MgSO4, filtered, and the filtrated was concentrated in vacuo. The crude material was purified by flash chromatography to yield [1-(2-Benzylamino-5-methyl-phenylcarbamoyl)-2-methyl-propyl]-carbamic acid tert-butyl ester.
